Hell you all,

I'm a relatively novice Mac Programmer and I would like to send and receive
simple ascii codes through the SCC port A using THINK's Lightspeed C.
I've tried many things already and the program below gives me "Pascal
argument wrong size" error.  Anyways, All I need to do is send commands
like "EX" or "BY1000" to a scanner.  I have the "inside Macintosh" Manuals,
but the examples are all in Pascal code.  Send mail if this topic has been
discussed to death.  Thanks a bunch.

main()
{
	sendinfo();
}

sendinfo()
{
	int setup,stuff, err;
	long int count = 1L;
	char message;
	char *ptr;
	SerShk flags;
	
	flags.fXOn = 1;
	flags.fCTS = 1;
	
	message = 't';
	ptr = &message;
	err = RAMSDOpen(sPortA);
	printf("%d\n",err);
	if (!err)
	{
		stuff = SerHShake (-7,flags);
		setup = baud300+data8+stop10+noParity;
		printf("%d\n",SerReset(-7,setup));
		stuff = FSWrite ( -7, count, ptr);
		printf("%d\n",stuff);
		printf("%ld\n",count);
	}
	RAMSDClose(sPortA);
	printf("%d\n",err);
}
